WHAT WE'RE LOOKING FOR
ESSENTIALS
Five or more years of experience as a software engineer, with deep expertise in object-oriented design and production-grade software development.
Strong experience with at least one strongly typed language, such as Kotlin, Java, C#, C++, or Rust. Python experience is useful but isn’t sufficient on its own.
Proven experience building and integrating blockchain infrastructure, such as wallets, transaction flows, or key management, into larger financial systems.
Experience integrating new systems into legacy or distributed environments without introducing instability or regressions.
Strong understanding of secure system design, particularly private key handling, signing, encryption, and operational controls.
Ability to quickly pick up unfamiliar tools or frameworks and adjust to changing technical priorities.
Clear communication skills and the ability to work effectively across engineering, product, and non-technical teams.
PREFERRED
Experience in FX, payments, or financial infrastructure.
YOU'LL THRIVE HERE IF
You're comfortable owning the roadmap yourself.
You own the outcome and you don't wait for permission to fix what's broken.
You're comfortable with ambiguity. Give you a problem, not a prescription, and you'll run with it.
You hold yourself to a high standard even when no one is watching. Quality and accountability aren't external expectations, they're internal ones.
You say what you mean. You're direct, but you lead with respect.
You’re comfortable operating across time zones with a globally distributed team, including colleagues based in APAC and EMEA.
